270 DBFS Content Interface Types

This chapter describes public types defined to support the DBMS_DBFS_CONTENT interface.

This chapter contains the following topics:


Using Content Types


Overview

The type definitions described in this chapter support the DBMS_DBFS_CONTENT interface in implementing metadata tables, packages, views, dependent application-side entities, and service-provider entities.


Security Model

The user can access the content operational and administrative interfaces (packages, types, tables, and so on) by way of the DBFS_ROLE. This role can be granted to users as needed.


Data Structures

Types that support the DBMS_DBFS_CONTENT interface include both Object and Table types.


DBMS_DBFS_CONTENT_CONTEXT_T Object Type

This type describes the execution context for the providers. It provides the user performing the operation with the Access Control List, the owner of the item(s), a timestamp for doing asof queries, and whether or not the item(s) are read_only. This type can be used both as input, in the case of path item creation functions, and output, in the case of path item query, or both.

Syntax

CREATE OR REPLACE TYPE dbms_dbfs_content_context_t
    AUTHID DEFINER
AS OBJECT (
    principal     VARCHAR2(32),
    acl           VARCHAR2(1024),
    owner         VARCHAR2(32),
    asof          TIMESTAMP,
    read_only     INTEGER);

Fields

Table 270-1 DBMS_DBFS_CONTENT_CONTEXT_T Fields

Field Description

principal

File system user

acl

Access control list

owner

Path item owner

asof

Timestamp

read_only

Nonzero if the path item is read-only



DBMS_DBFS_CONTENT_LIST_ITEM_T Object Type

This type describes a type to assist in listing the contents of a directory.

Syntax

CREATE OR REPLACE TYPE dbms_dbfs_content_list_item_t
    AUTHID DEFINER
AS OBJECT (
    path          VARCHAR2(1024),
    item_name     VARCHAR2(256),
    item_type     INTEGER);

Fields

Table 270-2 DBMS_DBFS_CONTENT_LIST_ITEM_T Fields

Field Description

path

Path to the path item

item_name

Name of the path item

item_type

Type of path item. (See DBMS_DBFS_CONTENT Constants - Path Name Types



DBMS_DBFS_CONTENT_PROPERTY_T Object Type

This type describes a single (name, value, typecode) property tuple. All properties (standard, optional, and user-defined) are described using such tuples.

The type is used by both the client-facing interfaces and by store providers for the DBMS_DBFS_CONTENT interface.

Syntax

CREATE OR REPLACE TYPE dbms_dbfs_content_property_t
    AUTHID DEFINER
AS OBJECT (
    propname     VARCHAR2(32),
    propvalue    VARCHAR2(1024),
    typecode     INTEGER);

Fields

Table 270-3 DBMS_DBFS_CONTENT_PROPERTY_T Fields

Field Description

prop_name

Name of property

prop_value

Value of property

typecode

Property type (See Constants in DBMS_TYPES)



DBMS_DBFS_CONTENT_LIST_ITEMS_T Table Type

This type is a variable-sized array of DBMS_DBFS_CONTENT_LIST_ITEM_T Object Type. It is used by both the client-facing interfaces and by store providers for the DBMS_DBFS_CONTENT interface.

Syntax

CREATE OR REPLACE TYPE dbms_dbfs_content_list_items_t AS
    TABLE OF dbms_dbfs_content_list_item_t;

DBMS_DBFS_CONTENT_PROPERTIES_T Table Type

This type is a variable-sized array of property tuples of DBMS_DBFS_CONTENT_PROPERTY_T Object Type. It is used by both the client-facing interfaces and by store providers for the DBMS_DBFS_CONTENT interface.

Syntax

CREATE OR REPLACE TYPE dbms_dbfs_content_properties_t AS
    TABLE OF dbms_dbfs_content_property_t;

DBMS_DBFS_CONTENT_RAW_T Table Type

This type is an array of RAW. It is to enable RAW data transport for batch interfaces in the DBMS_DBFS_CONTENT interface.

Syntax

CREATE OR REPLACE TYPE dbms_dbfs_content_raw_t AS
    TABLE OF RAW(32767);
